Functions

func Between

func Between(t, min, max time.Time) bool

Between 检查给定的时间是否处于某一时间区间内(左右都不包含!!!)

参考: 【收藏】开发常用的 10 个通用函数 https://mp.weixin.qq.com/s/tvy9L-pb_8WFWAmA9u-bMg

e.g. (cur, cur, cur.Add(time.Second)) => false (cur, cur.Add(-time.Second), cur.Add(time.Second)) => true

func ClearInterval

func ClearInterval(ticker *time.Ticker)

func ClearTimeout

func ClearTimeout(timer *time.Timer)

func ConvertByLocation

func ConvertByLocation(t time.Time, loc *time.Location) (time.Time, error)

ConvertByLocation 时区转换

@param loc 目标时区(不能为nil!!!)

e.g. UTC+8 转 UTC+0 2022-05-05 14:33:40.562899 +0800 CST m=+0.001585418 => 2022-05-05 06:33:40.562899 +0000 UTC

func ConvertToLocalLocation

func ConvertToLocalLocation(t time.Time) time.Time

ConvertToLocalLocation 转换为本地时区的时间.

func ConvertToUTC

func ConvertToUTC(t time.Time) time.Time

func CorrectSystemTime

func CorrectSystemTime(rootPassword string) (t time.Time, err error)

CorrectSystemTime (根据网络时间)纠正系统时间

func FormatCurrentTime

func FormatCurrentTime(formats ...TimeFormat) string

FormatCurrentTime 格式化当前时间为字符串

e.g. () => "2022-08-13 14:54:44.336" ("") => ""

func FormatDurationToString

func FormatDurationToString(t time.Duration) string

FormatDurationToString

PS: (1) %v 和 %s 都可以; (2) strKit.ToString 也支持.

e.g. (time.Minute*63 + time.Second*15) => "1h3m15s"

func FormatTimeToString

func FormatTimeToString(t time.Time, format TimeFormat) string

FormatTimeToString 格式化时间为字符串

@param t 不用担心t为nil的情况,详见下面的说明 @param formats 不传的话用默认值;传多个(包括一个)的话用第一个

一个方法如果接受类型为time.Time的参数,那么不用考虑该参数为nil的情况,因为: (1)time.Time类型变量的零值不为nil; (2)调用时,该参数位置不能直接传参nil(IDEA报错:Cannot use 'nil' as the type time.Time); (3)time.Time类型变量不能被赋值为nil(IDEA报错:Cannot use 'nil' as the type time.Time)。

func GetNetworkTime

func GetNetworkTime() (time.Time, string, error)

GetNetworkTime 获取网络时间.

PS: 获取不到的话,返回机器时间.

func GetSystemTime

func GetSystemTime() time.Time

GetSystemTime 获取系统时间(机器时间;本地时间;time.Local).

func LoadLocation

func LoadLocation(name string) (*time.Location, error)

LoadLocation

LoadLocation的输入参数的取值,除了该函数的源代码中可看到的”UTC”、”Local”,其余的值其实是遵照“IANA Time Zone”的规则,可以解压$GOROOT/lib/time/zoneinfo.zip 这个文件打开查看。 在Asia这个目录,我看到了Chongqing,Hong_Kong,但没Beijing。在国外获取中国北京时间,要用”PRC”,当然”Asia/Chongqing”也是个方法 参考:https://blog.csdn.net/qq_26981997/article/details/53454606

@param name e.g. "Asia/Chongqing"

func NewCron

func NewCron(spec string, task func()) (*cron.Cron, cron.EntryID, error)

NewCron

@param spec "@every 10s" || "@every 1m",更多可参考"Golang - 1.docx"

@return 第1个返回值: 可以调用 Run() 或 Start() 以启动.(Run()会阻塞调用此方法的goroutine;Start()不会阻塞)

e.g. spec == "@every 10s"

在调用Start()或Run()的那个瞬间开始计时,每隔10s执行1次传参task.

func ParseDurationString added in v2.0.9

func ParseDurationString(str string) (time.Duration, error)

ParseDurationString string => time.Duration

@param str e.g."300ms"、"-1.5h"、"2h45m"

func ParseTimeString added in v2.0.9

func ParseTimeString(layout, str string, args ...*time.Location) (time.Time, error)

ParseTimeString 类型转换: string => time.Time

@param layout 时间格式 @param str 要解析的时间字符串

func SetInterval

func SetInterval(fun func(t time.Time), duration time.Duration) *time.Ticker

SetInterval

参考: golang定时器函数 每隔几分钟执行一个函数 https://www.cnblogs.com/niuben/p/14368715.html

func SetSystemTime

func SetSystemTime(t time.Time, rootPassword string) error

SetSystemTime 设置系统时间(机器时间)

PS: (1) 通过date命令设置root权限,需要root权限. (2) 只能精确到"秒".

@param password root用户的密码

func SetTimeout

func SetTimeout(fun func(), duration time.Duration) *time.Timer

SetTimeout

参考: golang定时器函数 每隔几分钟执行一个函数

https://www.cnblogs.com/niuben/p/14368715.html

GO语言提前取消定时器

func ToRelativeString added in v2.0.9

func ToRelativeString(t time.Time) string

ToRelativeString

e.g. timeKit.ToRelativeString(time.Now().Add(time.Hour * -16)) => "16 hours ago" timeKit.ToRelativeString(time.Now().Add(time.Hour * 16)) => "15 hours from now" timeKit.ToRelativeString(time.Now().Add(time.Hour * 24 * 21)) => "2 weeks from now" timeKit.ToRelativeString(time.Now().Add(time.Hour*24*21 + time.Second)) => "3 weeks from now"
